Subject RE: [IBO] Query 3 times slower in 5.9 as compared with 4.21

TIB_Cursor should always return true for Eof when zero records were found. 

 

Would you please send me a sample app that reproduces this problem?

 

Thanks,

Hi Jason,

I finally have some time to try the cursor.  In the test application, its certainly giving a 10 fold improvement.  When I plug it into production code.  When some sqls  do not return data (ie zero records)  the

eof = false,
bof = true  and
recordcount = 0

Any ideas why.  For other queries, eof is true when the sql returns no records.

Regards

Rohit

Rohit,

That is a rather large jump in versions of IBO so it could be any number of
things causing this.

Would you be able to have me do a remote support session?

I'm sure I can get things working more as you are used to before.

Also, is it possible you can use a TIB_Cursor for that query?
This would eliminate many other possible things because it is simple
unidirectional access without all of the buffering overhead.

PS. I apologize for my delay in responding.

Thanks,
Jason Wharton

We have just upgraded IBO from 4.21 to 5.9. We are finding that even
the simplest of queries (such as fetch one record using primary key) is
3.5 times slower than before.

This happens whether we use FB 1.5 or FB 3.0.1

I have looked at published properties and cant see any differences. Any
clues anyone ?

Regards

Rohit
